Deficient Monitoring |
On 12/14/2024, M1W lost commercial power to AWPF and communications at IWF due to severe weather. As a result, M1W was unable to collect the required daily coliform sample from PWPS. While the requirement is based on a 7-day median and historically there have been no exceedances, M1W collected samples from the DIWs on 12/16 and 12/17 which were all ND. |

Deficient Reporting |
On April 26, 2025, the daily effluent Total Coliform sample was not collected due to a miscommunication between multiple staff members that were onsite that day. Staff reviewed the sampling requirements and are changing procedures and documentation to minimize chances of this occurring again in the future. |

Order Conditions |
During the month of December LOWRF was experiencing low online UVT%. On seven different days were saw numbers below 55%. We noticed that our grab samples were greater then 2% from our online analyzer. Once we adjusted the online probe to match our bench top grab the UVT% seem to be holding about 55%. However, water was still being delivered to users downstream. Online UVT% Below 55%- 12/1/2024- 53.8% 12/8/2024- 51.9% 12/15/2024- 53.3% 12/2/2024- 54.3% (grab 59.3%) 12/9/2024- 53.9 (grab 56.1%) 12/16/2024- 53.8% 12/3/2024-54.8 % From 12/15/2024- 12/19/2024 water deliveries were stopped to downstream users. However, from 12/1-12/9/2024 water was being delivered and grab samples were above 55% on the 12/2,12/9 and 12/16/2024. The probe was adjusted on 12/9/2024. We are still waiting for conformation from the State of our minimum UVT% requirement for the plant. On December 9th, we had a 10,000 gallons Recycle Water Effluent spill on Los Osos Valley rd and South Bay blvd. Spilled Recycle Water Effluent went into two different storm drains. We confirmed with our Storm water coordinator that the storm drains did not lead into a body of water. The water was followed to a storm water retention pond to evaporate/percolate. |
